The first recall I am posting regarding prepared salads is a new recall:
"Recall issued for pre-packaged salads"
QuoteSeveral varieties of prepackaged salads are being recalled due to the possibility of Listeria, the Food and Drug Administration said.
Apio, Inc. of Guadalupe, California is voluntarily recalling five varieties of Eat Smart Single-Serve Salad Shake Ups with a "Best Before" date of Dec. 14 after a random sample tested positive for Listeria Monocytogenes.
The company said it is recalling all products produced on the same production line on the same day as that sample out of precaution.
The salads were distributed in Florida, Arizona, California, Colorado, Kansas, Iowa, Oklahoma, Oregon, Texas, Utah, and Washington.
The article lists the specific products being recalled. Though at this point...the salad has passed its "Best Before" date so if you still have it in your refrigerator, you're not going to eat that, are you? 
The second recall in the news is regarding the recent romaine lettuce recall. A farm which may have been a source of the contaminated lettuce has issued a wider recall of its produce:
"The Farm Connected To The Romaine E.Coli Outbreak Is Now Recalling Its Cauliflower"
QuoteThe California farm at least partially responsible for the most recent romaine e.coli scare is now recalling its cauliflower, as well as its red- and green-leaf lettuce, USA Today reports.
The Adam Bros. Farms of Santa Maria, CA, were identified publicly for the first time by the FDA last Thursday...
The potentially affected cauliflower was harvested in California from November 27 through 30 and shipped to wholesalers across Arizona, California, Illinois, Louisiana, Maryland, North Carolina, New Jersey, New York, Ohio, and Pennsylvania, as well as to Canada and Mexico. The lettuces went out to California, Colorado, Texas, Oregon, Pennsylvania, Washington, and Canada.
